- 2,4-DPO makes it possible in particular to obtain an aesthetic improvement of the patient treated.
- the treatment can be curative, it is nevertheless preferably used in a preventive manner, that is to say during the period during which the structuring occurs and, consequently, the accumulation of collagen, this taking place in particular during the healing period.
- 2,4-DPO can be used for the preparation of a therapeutic composition in a form which can be administered topically, transdermally or intradermally.
- physiologically acceptable salts is meant according to the invention, addition salts of an acid such as those of sulfuric, hydrochloric, phosphoric, acetic, benzoic, salicylic, glycolic, aceturic, succinic, nicotinic, tartaric acid. , maleic, methane sulfonic, picric and lactic.
- an acid such as those of sulfuric, hydrochloric, phosphoric, acetic, benzoic, salicylic, glycolic, aceturic, succinic, nicotinic, tartaric acid.
- maleic, methane sulfonic, picric and lactic is generally between 0.0001 and 5% by weight, and preferably between 0.01 and 2% by weight relative the total weight of the composition.
- the vehicle can be very varied in nature but is preferably a physiologically acceptable medium for topical application, of course compatible with the active substance.
- 2,4-DPO can be found in this medium either in the dissolved state or in the dispersed state, in particular in micronized form.
- the physiologically acceptable medium can consist of water or a mixture of water and a solvent or a mixture of solvents.
- solvents which can be used, mention may in particular be made of lower C r C 4 alcohols such as ethanol, isopropanol, tert-butanol, alkylene glycols, alkylene glycol and dialkylene glycol alkyl ethers such as monoethyl ether d ethylene glycol, propylene glycol monomethyl ether, diethylene glycol monoethyl ether.
- These compositions intended for topical application can also contain at least one conventional additive or an active principle.
- UV.A and UV.B filters such as methoxycinnamates and benzophenone derivatives, antioxidants and / or free radical scavengers such as DMSO, ⁇ -tocopherol, BHA, BHT, superoxide dismutase, hydrating agents such as urea, glycerin, lactic acid, hydroxy acids, thiamorpholinone and its derivatives and pyrrolidone carboxylic acid derivatives, in particular its sodium and potassium, steroidal and non-steroidal anti-inflammatory agents such as hydrocortisone, ⁇ -methasone, dexamethasone, acetyl salicylic acid, indomethacin, isoprofen, vitamin D or niflumic acid, and antibacterials such as those belonging to the group of macrolides, pyranosides and tetracyclines such as erythromycin.
- UV.A and UV.B filters such as methoxycinnamates and benzophenone derivatives,
- compositions may also contain preservatives, stabilizers, pH regulators, osmotic pressure modifiers and emulsifiers.
- compositions intended for topical application based on 2,4-DPO can be presented in different forms such as for example in the form of lotions, gels, mousses, vesicular dispersions, sprays or aerosol mousses.
- compositions can also be in the form of gelled or thickened compositions.
- gelled compositions mention may in particular be made of those which are essentially aqueous, gelled with heterobiopolysaccharides such as xanthan gum, scleroglucans or cellulose derivatives and in particular cellulose ethers, or hydroalcoholic compositions gelled with polyhydroxyethylacrylates or methacrylates.
- thickened aqueous compositions there may be mentioned those obtained in particular using a polyacrylic acid crosslinked with a polyfunctional agent such as those sold under the names of "Carbopol®" by the company Goodrich. It is however of course possible to use as thickening agent any agent usually used in pharmacy or dermo-pharm acie.
- 2,4-DPO is generally applied to the parts of the body to be treated at a rate of 0.0001 to 5 mg / kg / day and preferably from 0.001 to 1 mg / kg / day.
- the treatment is generally continued throughout the period during which the accumulation of collagen occurs and may possibly be continued for 90 days after this.
- 2,4-DPO for the preparation of therapeutic compositions intended for administration by transdermal route.
- the proportion of 2,4-DPO is then generally between 0.001 and 5% and preferably between 0.01 and 2% relative to the total weight of the composition.
- the excipient used in these compositions is generally chosen from vinyl copolymers or copolymers, optionally added with a penetration promoter.
- compositions intended for transdermal application can in particular be administered using a self-adhesive system adhering to the skin and ensuring the continuous passage, for at least 24 hours, of a controlled quantity of active substance, through the skin, into the bloodstream.
- 2,4-DPO can also be used for the preparation of therapeutic compositions intended for administration by the intradermal route.
- the proportion of 2,4-DPO is then generally between 0.0001 and 5% by weight, and preferably between 0.01 and 1% by weight relative to the total weight of the composition. 2,4-DPO is then in soluble form in a physiologically acceptable vehicle such as physiological saline.
- compositions intended for intradermal administration can also comprise various therapeutic agents such as, for example, antibacterial agents, antioxidant agents and anti-inflammatory drugs, steroid and non-steroid.
- 2,4-DPO is generally administered intradermally at a dose less than or equal to 5 mg / kg / day, and preferably between 0.0001 and 1 mg / kg / day.
